Air to Ground terrestrial Internet Connectivity Terrestrial based Direct Air to Ground Internet Connectivity: Use of two license exempt frequencies (ISM Band): 2,4 GHz – European legislation mandates maximum output power <= 100mW EIRP. Can be used without limitation in Europe. 5,8 GHz – European legislation permits a maximum output power of up to 4W EIRP. However this requires specific approval of regulators as it’s Broadband Fixed Wireless Access 15 March, 2011 Direct Air to Ground Introduction FM PT48 Chart 4
